Apr 25, 2013 mill, produced by Nippon Eirich, and the Vertimill, produced by Metso. Grinding to below 40 lm in GIS mills or ball mills is usually not recommended. In their product literature, Metso give 40 lm as the lower end of the ‘‘optimal’’ P80 range for Vertimills. At lower product sizes, both tower mills and ball mills will overgrind ﬁnes.
1) Ball mill is an efficient tool for grinding many materials into fine powder. 2) The ball mill is used to grind many kinds of mine and other materials, or to select the mine. 3) Ball mill is widely used in building material, and chemical industry. 4) There are two ways of grinding the dry way and the wet way.

Ball Mill Grate Discharge Type In a grate discharge ball mill, a grate is installed at discharge end of the ball mill which classifies ground particles and permits particles with a size smaller than grate openings size to pass and leave the mill. The larger particles will be kept inside the mill for further breakage.
Grinding materials to a nano-scale is an important aspect of quality control and R D. AZoM speaks to Dr. Tanja Butt from RETSCH GmbH about the benefits of using High Energy Ball Mills instead of Planetary Ball Mills.
Cylindrical zirconia or stainless-steel grinding media should be used for effective grinding of the powder. Union Process Attritor Mill. The attritor mill is a wet grinding attrition mill. It differs from conventional ball mills as it uses much smaller media with diameter less than 5mm, leading to greater media-material contact area.
Involves feeding rock particles and water into the grinding mill containing a fraction of steel balls usually below 10 and running at a fraction of its critical speed. The slurry and ball charge adheres to the walls of the mill before cascading off at a given angle causing impact and fragmenting the ore (Nunez F, 2011).
